Abstract:
By a completely independent analytic calculation made in general covariant gauge we confirm the known result for the massless αs 3\alpha_s~3 correction to RhadR_{had} and check explicitly its gauge independence. We extend the calculations to include contributions due to a hypothetical existence of a colour octet of (light) neutral fermions known also under the name of gluinos.
